It’s really tough to say. In RDR1 it’s said that he was involved, but in RDR2 he’s never mentioned once. My theory is that since RDR1 was written well before the second game, R* had planned for him to be involved but due to the passing of the Voice Actor who played Landon Ricketts, I think the idea was scrapped, which is why he’s not mentioned as being involved in RDR2.
